The Manufacturer Process of Ultrathin BGA Package Substrates.

The manufacturing process of ultra-thin BGA packaging substrates is a highly refined and multi-step process, ensuring that each substrate meets high quality and performance standards. The following are the main steps in the manufacturing process, each with its key role:

The first step in the manufacturing process is substrate preparation. Typically, the substrate is made of fiberglass reinforced epoxy (FR4), or other materials such as ceramic or polyimide depending on application needs. Substrate materials must meet strict thickness and flatness requirements to ensure the quality of the final product. Substrates are typically cleaned and surface treated first to remove any impurities that may affect subsequent processes.

In the manufacturing of multi-layer PCBs, layer alignment is a crucial step. The conductive patterns on each layer must be precisely aligned to ensure correct electrical connections and signal integrity. The alignment process typically uses optical alignment systems, which can provide sub-micron accuracy. The aligned layers are temporarily bonded together in preparation for further processing.

The formation of conductive traces is achieved through etching or printing techniques. Etching involves covering the surface of a substrate with a layer of photosensitive material, exposing and developing it through a mask to pattern the conductive areas that need to be retained, and then etching away the unprotected copper layer in a chemical solution. Printing technology uses conductive ink to print patterns directly on the substrate, which is suitable for flexible substrates for some special applications.

In order to mount electronic components and make electrical connections between multiple layers, holes need to be drilled into the substrate. The diameter and position accuracy of these holes are critical, especially in high-density BGA packages. Drilling is typically done using high-precision mechanical drills or laser drills, which can process tiny hole diameters and ensure the exact location and size of each hole.

The solder cap layer is coated to protect the conductive pattern from the external environment and prevent short circuits during the soldering process. The solder cap layer is usually a green or other colored epoxy material that covers a non-conductive area on the surface of the substrate. After application, the weld cap layer needs to be cured, usually by heat treatment.

During the component assembly process, electronic components are placed precisely in designated locations on the substrate. This process typically uses automated equipment, such as a pick-and-place machine, to place components on pads pre-coated with solder paste. The solder paste melts during the subsequent reflow soldering process, forming a strong electrical and mechanical connection.

The final step in the manufacturing process is testing. Each substrate must undergo rigorous electrical and functional testing to ensure there are no manufacturing defects. These tests include open and short circuit tests, functional tests and thermal cycle tests to ensure that each substrate can work stably under various operating conditions.

Through the above-mentioned detailed manufacturing steps, the ultra-thin BGA packaging substrate can achieve high-density and high-performance requirements and meet the stringent requirements for reliability and precision of modern electronic equipment.
